Name:
Named in 1987 by V.I. Popova, V.A. Popov, N.S. Rudashevskiy, S.F. Glavatskikh, V.O. Polyakov, A.F. Bushmakin in honor of Sofia Ivanovna Naboko (Софьи Ивановны Набоко) (13 September 1909, St Petersburg, Russian Empire - 2005), Institute of Volcanology, Petropavlovsk-Kamchatskii, Russia. Naboko was an investigator of postvolcanic processes of Kamchatka and collected the first samples of the mineral. The mineral sophiite is also named for her.
